It took Wang Ling three more hours before he finally finished reinforcing his cultivation realm. It sapped him out of his spirit stones and one Golden Qi pill but he had finally finished his cultivation.

"Huu!"

Wang Ling exhaled a deep breath. His breakthrough had come so fast that even he didn't expect it to end this fast. He expected he would need to spend at least two days the least, but who would've thought that he would finished in less than a day.

Approximately twenty-two hours had passed and Wang Ling had finally completed his breakthrough in his cultivation.

"I'm still at the early stages of earth root stage so my roots is still at the first layer of the spirit ocean."

The cultivation stages in Celestial Spirit Realm is divided in [Three Major Phases]and [Two Boundary Realms].

The three major phases are: [Foundational Phase], [Saint Phase], and [Celestial Phase].

There are three stages in every phase as Wang Ling is still in the foundational phase the three stages he needs to passed are: earth root stage, sky root stage, and energy palace stage.

Every stage also has their sub levels namely: [Early], [Middle], [Late], and[Pinnacle].

Wang Ling is only an early earth root stage cultivator at the moment meaning he's at the very bottom of the power ranking. However, he was not in a rush as he knows that he was still at the starting line of cultivation.

In earth root stage, the only goal is to penetrate the layer or barriers of each sub levels. Wang Ling is an early earth root stage so that means he needs to break each and every barrier in order to reach the next level of cultivation.

If one day he reaches the fourth layer of earth root stage, thereby reaching the barrier of the sky root stage. That would mean it was time for him to advance in cultivation. But that would only come after he actually reaches pinnacle.

Wang Ling felt great as he observed the spirit qi that was flowing in his meridians. His delight was unhidden and was open. However, a dangerous light flashes in the corner of his eyes.

"It is time to cultivate and become a devil!" he made a terrifying remark and subsequently began diving through his memories of heaven defying body refinement technique.

"[True Tyrant Body], [Helios Body], [Adamantine Crystalline Body Refinement Technique] is all good, but this is the only one for me in this life." He scoured his memory until a single book appeared in his mind.

[Hell Dominator Body], a smile emerged on Wang Ling's face. This was a technique he had been itching to train in since he got in after massacring through hordes of Vile Devil Dragons.

The Hell Dominator Body as the name implies was a technique that will let him dominate Hell once he went there. The technique will let him cultivate the bloodline of the true devil and gain the [Twelve-winged Devil God]formed in the end.

From what ancient texts foretold, devils have a strict hierarchy in terms of their bloodline. Two-winged devils are the lowest of the low while Twelve-winged devils was their god.

When he acquired this technique, he was already itching to try and cultivate it but because of the strict requirements. Wang Ling had no choice but to drop the idea of cultivating it.

The first requirement was the presence of supreme spirit qi in the foundational phase. This alone made him want to vomit blood back then because he thought that such a thing was utter nonsense, but now, he was dying to cultivate it as fast as possible.

"Hehe, I will someday go and explore Hell realm so why not go there as a god? It's not that bad of an idea to go there while being worshipped." Wang Ling mischievously thought to himself.

Well the idea of being a go in Hell realm is not so bad of an idea but he actually chose cultivation this technique because it was the strongest in the long run. Most body refinement technique tends to only last in usefulness when they reach a certain realm.

Body refinement techniques that is in his possession is only Saint Grade. The Hell Dominator Body is above that. For someone to have the chance to cultivate to becoming a god, now that's the true peak he'd been searching for.

The Saint Grade body refinement technique he had were all first class and could become treasures if leaked. However, Wang Ling was just feeling some kind of connection with the Hell Dominator Body.

This was a technique he couldn't cultivate in his previous life, now that he has the chance to properly cultivate it, he will not give up this chance. Wang Ling nodded his head and made up his mind.

He took out the Lustrous Devil Branch from his storage ring. He held it with his right hand. The Lustrous Devil Branch was only a few inches big and looked like an ordinary branch, the only difference is that it was emitting lustrous black light.

Wang Ling began circulating his supreme spirit qi and started absorbing the devious and malicious energy inside.

The Lustrous Devil Branch was a treasure of the world and contains a tyrannical qi of slaughter. It was usually used in forging weapons that leans on the yin attribute and no one would even dream of using it for cultivating except if you're a devil cultivator.

The qi of slaughter was very harmful for Wang Ling's body, and he was well aware of this fact. But he kept absorbing the qi inside either way. His forehead started forming beads of sweat as an acute pain attacked his mind.

The devilish qi was starting to attack him for the inside, one wrong step and he'll suffer a severe backlash. Pinnacle cultivator or not, he was in a dangerous situation.

He slowly refined the devilish qi he was absorbing from the Lustrous Devil Branch and after an hour, the luster on the branch began to fade. His face that was contorted with pain didn't ease up.

The devilish qi was still inside his body and was wreaking havoc in his meridians and body. But then, his supreme spirit qi started surging up and began suppressing the devilish qi. The devilish qi was quickly assimilated into his body and then into his qi pillars and spirit ocean where his spirit qi is densest.

The devilish qi was only a low-level kind of energy so it was easily assimilated in his body. Wang Ling opened his eyes and realized that he only used up barely an hour and a half to refine a treasure.

"That should do it! My body won't be overwhelmed that easily. After all, there's devilish qi in my meridians in my body and it should suppress the force of the oncoming [Hellish Qi]."

He had previously bought four different kind of treasures. These treasures were meant to alleviate the pain of cultivating the Hell Dominator Body.

Wang Ling was well aware of the searing pain of cultivating this technique so he made preparation early on. Some of the treasures he bought was also to supplement his future cultivation.

The Blood Revolution Pill he failed to buy was now also in his possession. He needed the Lustrous Devil Branch so that his body will have some kind of low-level devilish qi that will help him assimilate the hellish qi.

He then took out the Devil Tree Fruit and ate in one bite. The Devil Tree Fruit was then assimilated by his body after two hours. The denseness of devilish qi began to rise inside his body and soon enough, he found the amount to be enough and started circulating the Hell Dominator Body.

Gong!

Wang Ling felt a giant bell suddenly going off inside his head. The loud sound resonated with his supreme qi, which made his qi pillars, meridians, and spirit ocean tremble.

Gong!

As the second gong was heard. A slight rift was created in his body and a new energy started seeping out of this rift. Hellish qi has finally started pouring in.

The rift was located in the middle of his qi pillars and on top of the spirit ocean. The hellish qi began seeping out of the rift slowly and gave Wang Ling a soul tearing pain.

"Argh! This is something else! The hellish qi is simply too tyrannical and there's aura of slaughter mixed in with the pure hellish qi!"

Hellish qi, one of the purest qi that contains the essence of destruction and slaughter.

The supreme spirit qi can adapt to any form of energy. The supreme sprit qi has no impurity and this is the only reason why a normal human being like him is able to cultivate such a powerful technique like this.

If someone dared cultivate it without supreme spirit qi, the clash of impurities and the hellish qi will result in some unwanted results.

That person's limb will be torn off and his body will be destroyed, his soul will be torn to pieces and his whole being would disappear. Wang Ling was only surviving right now because his spirit qi was the purest and most powerful of them all.

His mind, will, perseverance, and determination was also top-notched.

Then, even before he was able to completely assimilate with the oncoming hellish qi that was supposed to little by little, another sound was heard.

Gong!

This time, the small rift expanded and engulfed the entire space where his spirit ocean and qi pillars were situated. The space was filled with hellish qi that's threatening him to tear his soul.

"This is not good!"

Working his qi pillars and spirit ocean to the fullest. The hellish qi that was running rampant started getting absorbed by both his qi pillars and Spirit Ocean.

The previously golden ocean and the pure golden qi pillars began to be dyed by a deep color of black. The black hellish qi began assimilating with his spirit ocean, qi pillars, meridians, and even his body.

Crack!

His body began to change as the impurities that is held within his body was flushed out by the hellish qi.

The hellish qi started rushing to every corner of his body, every muscle of his was bathe with hellish qi. Like its name, the hellish qi Wang Ling absorbed, devoured his supreme spirit qi without trouble, and because his spirit qi was pure, no backlash happened.

The brutal spirit qi made Wang Ling experienced an excruciating pain, yet his face did not show any change. His countenance showed a serene and tranquil image as if the pain did not faze him one bit.

He acted normal as he calmed his mind, with two different type of qi mixing together Wang Ling did not have the leisure of complaining about the pain.

Beads of sweat started appearing on his forehead, while his back dampened from the sweat. It felt like everything was burning and the wails of souls, resonated within his mind.

The essence of slaughter and destruction was beginning to assimilate with his being. Soon enough, the wails of souls was no longer a problem.

Slimy and stinky black substance started seeping out of his pores as his body throbbed. The black substance then flowed out of his body and into the ground, the stench could make anyone run away.

Moments later, Wang Ling opened his eyes, his deep black eyes now had a devilish red glow. Although it was not that apparent if one didn't observe it intently.

"This is too extreme."

He had yet to even start with the level one cultivation of Hell Dominator Body yet he was already this exhausted. What's more, the power this technique holds was simply too immense that even he had to acknowledge it as the most tyrannical force he had ever faced in his life.

What he had just cultivated was called hellish qi, and it was the highest qi of Hell realm. There're a lot of different cultivation technique in the Celestial Spirit realm.

Most of which have their own unique traits. Some cultivate the energy of the sun, some the tundra and these cultivation techniques usually utilizes yuan qi that's not available to normal people.

The one he cultivates happens to be the qi of hell. Inside his body, the qi pillar which used to be golden was now part black, it was the same with the spirit ocean. Half of the ocean's surface was black while the other was gold.

Letting out a deep breath, Wang Ling felt a change within his body. Even if it wasn't visible to the naked eye, he was sure that his body was cleanse out of impurities once more.

Wang Ling opened his eyes and subsequently smelled the stench in his house. This made him want to run away from his room but he realized that the stench was coming from him so running away wouldn't really do anything.

He sighed and went out of his room. He found out that the sky was actually dark already.

"Did refining the two treasures and assimilating the hellish qi took so long?"

Either way, whether it be morning or night. Wang Ling would still take a bath. Calling to maids, Wang Ling ordered them to prepare a bath as quickly as possible.

The two maids smelled the stench on Wang Ling's body and immediately complied.

Wang Ling, had officially came out of seclusion.

Wang Ling entered as a human and came out as a pseudo-devil.
